The Refil-Plex is a machine commonly used to trim excess material (after being glued), chamfer, radius and shape the edge of the slabs. In recent years, this machinery has evolved with the advent of diamond cutters that can also be adapted to manual push operations, in fact, although the manual push is not constant, we have still managed to obtain optimal finishes. Therefore, thanks to the combination of its structure (small but solid and free from vibrations) technology (balanced high-performance motors) and the insertion of new cutters, the simple and silent Refil-Plex has a great working potential.
